I keep having the feeling that some competent Villains manage to exploit my river blockbets by turning large portions of their range into bluffs. I am currently very unsure how to deal with raised blockbets and currently I am overfolding. I can imagine that in general, I might want to call with those hands that unblock Villain's bluffs. However, on the type of runout where I want to blockbet in the first place, I often times have a hard time finding a lot of bluffs in Villain's range at all.

The hand example should be standard until the river. In retrospect, my flop raise could have been sized a bit larger. On the river, I feel like c/f is too weak and I don't want to c/c larger bets, hence blockbet to still extract value from AK/KQ/KT without a heart. How do I react to Villain's raise? Which types of hands to call here, which types of hands fold?

Any suggestions are welcome
